if im not mistaken, it means that if x is less than ln2 then y is equal to e^2
and if x is greater than or equal to ln2 then y is equal to 2
course, there is no basic question per say when you state an equation, does your book for this particular round of equations state something like If X is this (for example, 2), then what is y? If so you would be able to 'solve' it.
If not, the question may be simply asking you to explain the properties of the equation as i have posited above.
